Towards a Common UnderstandingCreating the Network-centric Environment

“From AIS to AIM”

“Worldwide Symposium on Enabling the Net-Centric Information Environment”

Introduction (1)

• ATM operations are a complex interaction of dissimilar activities• Frequently no physical links exist between them• In Europe the 100 main airports are:

• connected by approx. 600 airspace segments • controlled by 65 ATCC’s with many systems• operated by 38 ANSP’s with different cultures

• Terrestrial communications usually fixed point-to-point links• Information sharing often limited• Coordination & management frequently dysfunctional• No common situation picture of ATM operations exists

3

Introduction (2)

Lack of a common picture and effectivein-time communication and cooperation

Improved situational awareness would benefit all

ATM IS FACED WITH A PARADIGM SHIFT

LITTLE COST

Effective means of understanding and cooperation will result in reduced capacity loss and an increased system through-put

NEGATIVE IMPACT

4

The Paradigm Shift

CREATING THE PARADIGM SHIFT

• Establish culture of information sharing, to• Enable True system interoperability • Deliver a complete, accurate & temporal situation picture common to ground/air • Through evolution of the Net-centric information environment

5

Overview

The Net-centric Environment…………..

“the true Intranet of ATM”

• Challenge is to create a regulated environment covering multiple & diverse actors from

• ATM and non-ATM Domains

• The key to this Symposium

6

Overview

• Based on Net-centric Enterprise Architecture………

“light-weight, massively distributed, horizontally-applied architecture, that distributes components and/or services across an enterprise's

information value chain using Internet Technologies and other Network Protocols as the principal mechanism for supporting the distribution

and processing of information services”

• In ATM and SESAR especially referred to as the‘Concept of System Wide Information Management (SWIM)’

• Short/medium term evolution through Aeronautical Information Management - AIM

7

Aeronautical Information Management AIM

• Human AIM• Institutional AIM• Quality AIM• Digital AIM

8

What is AIM?

• Reflects changing ATM environment• Emphasis on flexibility & interoperability• Recognises need to transit from products to data• Envisages the “pooling” of selectable data for tailored

application from significantly expanded data sets• Is a Concept, a System & a Service

• WHAT, WHY and to an extent HOW• NOT WHO – for States/industry to decide

• Is short/medium term implementation of net-centric INF ENV described in SESAR ATM Master plan

• Forms basis of Eurocontrol CND IM Strategy, an elaboration of the Master Plan

9

AIM Basics

• Digital provision of quality information• Move towards a state of information sharing and

exchange• Based on Enterprise Architecture & Service Oriented

Architecture (SOA) concepts aligned with• SESAR• Trend towards Network Centric Operations

• Will follow & leverage existing global and open interoperability regulations & standards

• Time line to 2020 & transition to SWIM

10

AIM evolution

• Information On-demand• Information filtering based on location and time (4D) to

• support of future 4D trajectory management, and• collaborative decision making

• Static and dynamic information fusion• Seamless information sharing• Open solutions• Innovative digital services and products• Improved situational awareness

AIM IM Functions

• (generic) AIM Information Management Functions• Quality, Content & Distribution• Maintenance & updating• Exchange & access• Description & discovery• User identity & profile• Security & authentication• Notification• Digital data rights• Charges etc

• Each IM function implies information sharing• Extended Data Models to cover shared information

management requirements• Global rules & regulations are needed for safe & effective

management

18

Information Management In Europe

• Essential nature of IM reflected in SES Regulation

• Requires unbundling of services, an institutional change

• Further regulation such as aeronautical data quality on way

• The SESAR ATM Target Concept• Transition from ICAO Flight plan to 4D Business Trajectory

• Transition to Network Centric Operations

• Based on Service Oriented Architecture (SOA) principles

• Compliant with ICAO ATM Target Concept

• IM a key enabler of SESAR ATM Target Concept

• IM Strategy second pillar of Eurocontrol CND realignment

• Key component Reference Model for ATM IM: RM-ATM-IM

Conclusion

• AIM much more than “modern” AIS• Embraces ALL ATM information needs• Based on open requirements, open standards, and open

exchange models• Pace of change accelerated by SESAR & NextGen• SESAR & Eurocontrol IM Strategy in support will define

WHAT, WHEN, HOW but not WHO • Technology not the issue, institutional & resource issues

are• ICAO is key to standardised & harmonised global change

& management• Symposium marks the start in the Paradigm Shift
